Winter Interior Protection Again Mold and Mildew

Sta-Dri. I was told about these many years ago, for I neither have a heated garage, not a moisture controlled one. I bought two of these packets twenty years ago, and they are still working terrifically, for my storage area in town has for winter months, probably about 100% humidity — yet never a mold nor interior issue in my Corvettes.

While perhaps cheaper elsewhere, even at the company (sta-Dri.com) and including freight, it is $39.00 for the two large packets they recommend for a sports car.

I throw them in the car, one in the passenger footwell, one in the trunk every November (each on a piece of thin plastic), take them out when we are back to repetitive sunny days around May (the Pacific Northwest can be super damp six months a year).

At the end of the moisture season, I take them out, stick them on a rack in the oven at 250 degrees for eight hours, let them cool, place them in a zip lock bag until the next November. The same two pouches have worked perfectly for me all this time.

Haven’t used in a car but a Goldenrod dehumidifier heater should work too. Know people have used in boats and we use in our safe. Needs electricity though.

Hi, thanks for the idea. I'm just thinking about buying a dehumidifier for the car. Because I live in an area with high humidity most of the year, my car has a leather interior and I don't like the unpleasant odor due to the dampness. And I also found traces of mold in my trunk, so I'm sure the dehumidifier is what will help me solve this problem. Just in case, I consulted a local mold removal company that my friend recommended. Because I know that mold is very dangerous to health and it is difficult to get rid of it. But I got some advice and I hope it helps.

I had to store my Corvettes for decades within a concrete and metal unseated building. Regarding the first post above, every fall I would take four of those pouches (annually properly moisture-removed as per their instructions — super simple) and place two inside the cabin and two inside the trunk (pre C8’s of course) and then take them out when spring became nice. As we have lived all that time in Oregon, the home of often daily winter rains with 37 degree days and typical +90% humidity, in spite of those three bad things, not one Corvette ever got the slightest touch of mold nor mildew. Those pouches work exceptionally.

For about Grand this looks Cool for anyone storing for 3 to 5 months

It would work really well for some. But what happens when in the middle of the winter for those of us who are not snow bound, when we get a sunny winter day go for a ride. After we return, we close our car ack inside the air chamber with its say 45 degree temp at that time. Then the rains comes, the temperature drops and the humidity/moisture inside it remains (I did not see a dehumidifying component); in fact as the temp drops that humidity level increases. That is the beauty of the much cheaper pouches, is that they trap and contain the humidity within their pellets, keeping that moisture from from causing inside car model and mildew issues. They of course do not require electrically to work (which was the storage condition I had for four decades, e.g., no electricity).
